“…These results are similar to those for the Eastern Paris Basin (Négrel et al, 2006) and the Venetian region of northern Italy (Bellanca et al, 1997). They also support the conclusions of Dill et al (2009) who showed that mineral assemblages and Ca isotope abundances indicated a significant proportion of detrital material in the CTSS sediment to have been derived from mafic igneous sources.…”

“…The average Sr contents of the Greek evaporites presented in the current study (Sr avg = 11,393 ppm) are substantially higher compared to those of Spain, Poland, Austria, Persian Gulf and Israel evaporites, which display considerably lower Sr values (≤5000 ppm; [2]). In this context the Greek evaporites also exhibit higher Sr contents compared to those of the Maroni (Cyprus) and Arabian Gulf (Qatar) celestite-bearing evaporitic deposits, which present Sr contents ≤3000 ppm [11]. Despite their general Sr-rich nature, the Greek evaporites do not present compositional homogeneity with Sr contents ranging between 1099 and 64,265 ppm.…”

Greece is considered as one of the most common producers of gypsum-anhydrite in Europe. The low content of impurities of these evaporite minerals, their big reserves and the low cost of logistics costs makes them exploitable and applicable for a range of industrial uses. The current study endeavors to present the petrographic, mineralogical, geochemical and qualitative features of evaporite samples from seven selected localities of western Greece (Zakynthos Island, Filiates-Thesprotia, Etoloakarnania and Kyllini region) and Crete Island. The studied evaporitic rocks are classified as a mixture of gypsum and anhydrite, where gypsum predominates. Other minerals present in minor amounts include celestite ± calcite ± dolomite ± magnesite ± sanidine and quartz. Celestite (SrSO4) was detected in all studied samples. The highest celestite value (13.5%) corresponds to the region of Filiates, indicating that this deposit is prosperous for further research and potential Sr exploitation. Significant focus is also given on the assessment of the evaporite whiteness with respect to their mineralogical and geochemical composition. The aforementioned data aim to serve the dynamic Greek calcium sulphate industry by enhancing the evaporites’ prospects of industrial use, providing potential applications for those not already exploited.

“…Source of Strontium Sr is the main element of the celestine, and Sr isotope analysis is widely used to identify the sources of Sr in the celestine [1,18,23,91]. Most of the celestine deposits located around the world are mainly hosted in marine carbonates and evaporites [92,93], and the Sr isotope value of celestine is consistent with/or slightly different from that of coeval seawater [10], indicating that the formation of celestine deposits is closely related to seawater, and some authors state that the mineralization age of the deposit by comparing the Sr isotope ratio of celestine with that of seawater [2,27].…”

Geological and Geochemical Constraints on the Origin of the Sr Mineralization in Huayingshan Ore District, Chongqing, South China

There are many celestine deposits and mineralization points in the Huayingshan ore district which form the largest strontium resource base in China. Among these celestine deposits, the Yuxia and Xinglong are two of the larger deposits. Previous studies have displayed different views on the genesis of the celestine deposit in the Huayingshan ore district. In this study, we conducted field obversions, geochemistry, and fluid inclusion studies to investigate the sources of ore-forming matters and the metallogenic mechanism of the celestine deposit. Four types of fluid inclusion (FI), namely PL (pure liquid FI), PV (pure vapor FI), L-V (liquid-vapor two-phase FI), and L-V-S (liquid-vapor-solid three-phase FI) have been identified in celestine from different types of ore in the Xishan anticline. The ore-forming fluids belong to the NaCl-H2 O system with moderate to low temperature (190–220 °C) and moderate salinity (5–9 wt%, NaCl equiv.). Different types of ores were formed by the same period of hydrothermal activity, which is supported by the results of the microthermometer study. Geological, thermometric data, and published hydrogen and oxygen isotope results indicate that the hot brines associated with mineralization mainly originated from meteoric water and some of diagenetic fluid. The Sr (87Sr/86Sr = 0.7076–0.7078) and S (δ34S = 36.4–39.0) isotope values of celestine are consistent with those of the Jialingjiang Formation, indicating that ore metals in hot brines were predominantly derived from that formation. In situ analysis of celestine shows that there is a strong negative correlation between Sr and CaO (R2 = 0.95) and combined with mineralogical and isotope geochemical evidence, we concluded that the precipitation mechanism of celestine is the replacement of gypsum with Sr-rich hot brines. Based on the above research and the classification of celestine deposit type, we classified the celestine deposits in Huayingshan as being of hydrothermal type. The formation of celestine deposits can be divided into three periods: (1) evaporation period, forming the source bed; (2) hydrothermal activity period, forming celestine by replacement of gypsum with Sr-rich hot brines; (3) supergene period, where meteoric water dissolves orebodies and strontianization occurs.
